- LF-4-72-4A backward curved commercial centrifugal blower (1)13y

7 Jan 2019

Use a backward-curved centrifugal impeller to capture and guide external airflow into the volute.

The high-speed rotation of the impeller generates centrifugal force, pushing the air toward the air outlets, exhaust ducts, or other ventilation systems.

The excluded air flow creates a relatively low-pressure area, prompting more external air to enter the volute and achieving a continuous circulation of airflow.

It adopts an all-stainless steel shell and structure, which is high-temperature resistant and can work stably under high-temperature conditions such as industrial drying or heat treatment; the stainless steel volute can effectively reduce noise.

Using high-quality motors, the required power can be selected according to the fan's air volume, wind pressure, and operating conditions.

It drives the belt or rotating shaft to rotate efficiently and cooperates with the impeller to generate centrifugal force to absorb or discharge air.
